Adding modeled details to your piece can also be a distinctive way of decorating pottery. 

When your pot is leather hard, you can add sculpted and modeled details to your design.  This can add character and individuality to your work, making it truly one of a kind.

Modeled details on a pot can be added to hand built work or a wheel thrown piece.  The modeling can be added to the pot itself, or you might add a sculpted lid to a piece with an otherwise simple design.  Alternatively, you might like to add sculpted details to the handle of your piece. 

When decorating your pots with modeled details, the choices are endless.
